I rnocnss or rnonncme LIQUID roars.

of Baltimore, in the State of, Maryland,

have invented a certain new and usefullmk iquid Fuels, anddo-hereby declare that the following is a full, clear, and exact description thereof.

My invention relates particularly to pr ceesses for making fuels designed to be used in any desired manner, but it, has application especially to processes for making fuels adaptedto be used as a source of power, as for example fuels for burners .and motor fuels. The object of my invention is to provide processes. for making a fuel .OOIltiLlIllIlg a light hydrocarbon, as well as alcohol and an ingredient adapted to blend the same or to form a'solutionwith/ the hydrocarbon and alcohol. w further object of my inventlon is to provide processes for making a fuel of this I character which is of such a nature that Q59 only'a very small quantity of. the third ingredient is found necessary.

A further object is-toprovide processes for making a fuel of this character which contains -a large percenta e of. the light hydrocarbon, notwithstan ing the small percentage of the third-ingredient. j I A further. object of my invention is to provide processes for making a. fuel 'of'this character in which the third ingredient is acetylene; o

provide processes for. making a fuel of this character which vcontains dehydrated alcocertain ways'of carrying out the same herein. Furthermore, while my inventionisf ca pable of being carried: out inconnection with many diflerent types of-apparatu's, I have .shown only one type of apparatus for use vin Processes of Producing" A further object of my invention is to While my invention .is 'capableof .carried out in many difi'eren't ways, forthev purpose of illustration I-shall describe only I I I Specification of Letters Patent.

in connection with the same in the an? oompanying drawings,- in which The figureis a diagrammatic representa tion of an apparatus which may be used in connection with my invention.

For example, a fuelmade in accordance with my invention may be made as follows 50 c. 'c'. of ethyl alcohol, having a strength of 95% is added to an excess of calcium carbide, amounting usually to 10 grams, in a container 1, having a' valved inlet opening 2 and a valved outlet pipe 3. The calcium carbide is acted upon by the water in the alcohol so as to produce acetylene, a'portion to the top of the "container 1, and is then passedinto a mixture of 50' c. c. of gasolene let 3 located in the bottom of the container, and the calcium hydroxide and any unde-' composed calclum carbide. is filtered oif from the liquid, which is a dehydrated .alcohol having-astrength of approximately 99%,and containing approximately 1% of acetylene dissolved therein,that. is to say, a saturated solution ofacetylene. The alcohol thus produced is then mixed with the mixture of gasolene and kerosene, containing acetylene obtained as-above, thus providmg a fuel oil that remains homogeneous and which is advantageous for use as a motor fuel or for burners.

Another composition containing the dehydrated alcohol may be comprised of 50 c; c. .of the alcohol dehydrated as before,

50 cc. ofgasolene and40 c. c. of kerosene to} which no acetylene has been added.

As another mode of procedure in producof which dissolves in the alcohol while'the" balance is carried ofl by a tube 4:, connected ing fuels: in accordance with my invention, i

I may begin as. follows: 50 c. c. of ethyl alcohol, which may have been previously partially dehydrated or not, as desired,

-mixedwith 50 c. c. of gasolene and 40 c. 0. 0f "kerosene, are; introduced intcthe c0n- 'tainer 1, and an excess of calcium carbide, usually amounting to 10 grams, is then added thereto. The mixture is'then allowed to 1amples,ifitisdesired to add more acetylene,

' stand for one or more days, until eventually.

all of. the acetylene produced dissolves in the mixture. The contents of the container and any undecomposed calcium carbide,

thus leaving a homogeneous'mixture containing dehydrated al cohol, gasolene' and kerosene containing pp-roximately 1% .of acetylene. l

Furthermore, in either of the above exthis may be done by adding thereto loc. c. of acetone saturated with acetylene.

The dehydration ofthe alcohol very inaterially assists in the blending of the same with the'gasolene and kerosene and the acetylene contained in the mixture alsoassists, to some bility.

extent, in accomplishing the same end. a

The addition oftheacetylen'e'to thefuel', furthermore, assists in improving the charactor of the fuel by increasing its explosi- This isespecially advantageous where the fuel is-to be used'as a motor fuel. Where acetone is added, this also has a similar effect in increasing the readiness with which the mixture explodes when used as a fuel.

It will be understood'that. the dehydrated alcohol; need not necessarily be 1 ot-thestrength above referred to, but may be of any strength above the 95% strength ob tained "commercially.

It will be understood, however; that, 'instead of the gasolene and kerosene referred tom the above, examples, I .mayuse only 'gasolene, j
